Angelwing clam (Pholas orientalis) hydrolysate was prepared by hydrolysis using bromelain. The hydrolysate named as bromelain hydrolysate (BH) was then treated with β-cyclodextrin in the ratio of 1:0.8 (v/w) by physical mixing and kneading methods producing the physical mixed hydrolysate (PMH) and kneaded method hydrolysate (KMH), respectively. The masking effect of β-cyclodextrin on bitterness was evaluated based on sensory analysis, amino acid analysis and determination of flavor compound by gas chromatography- mass spectrometry (GC-MS) and field emission scanning electron microscope (FESEM). Sensory analysis showed that KMH has least bitter taste compared to BH. Amino acids analysis showed that hydrophobic amino acids content that contributed to the bitter taste were lower in KMH and PMH compared to BH. GC-MS analysis also showed that benzothiazole compounds were present in KMH. The absence of benzene, 1-phenyl-4-2-(2-cyano-2-phenylethyl) in KMH and PMH indicated that phenylalanine in BH had been masked by β-cyclodextrin. FESEM showed that the new solid phase formed by kneading method has a crystal structure which was completely different from the original morphology of BH and β-cyclodextrin. Therefore, the bitterness in BH had successfully been masked by β-cyclodextrin, thus indicates its potential to be used as food ingredient..

Mathew S, Zakaria ZA

Appl Microbiol Biotechnol, 2015 Jan;99(2):611-22.
PMID: 25467926 DOI: 10.1007/s00253-014-6242-1

Pyroligneous acid (PA) is a complex highly oxygenated aqueous liquid fraction obtained by the condensation of pyrolysis vapors, which result from the thermochemical breakdown or pyrolysis of plant biomass components such as cellulose, hemicellulose, and lignin. PA produced by the slow pyrolysis of plant biomass is a yellowish brown or dark brown liquid with acidic pH and usually comprises a complex mixture of guaiacols, catechols, syringols, phenols, vanillins, furans, pyrans, carboxaldehydes, hydroxyketones, sugars, alkyl aryl ethers, nitrogenated derivatives, alcohols, acetic acid, and other carboxylic acids. The phenolic components, namely guaiacol, alkyl guaiacols, syringol, and alkyl syringols, contribute to the smoky odor of PA. PA finds application in diverse areas, as antioxidant, antimicrobial, antiinflammatory, plant growth stimulator, coagulant for natural rubber, and termiticidal and pesticidal agent; is a source for valuable chemicals; and imparts a smoky flavor for food.

Monosodium glutamate daily oral supplementation: study of its effects on male reproductive system on rat model

Jubaidi FF, Mathialagan RD, Noor MM, Taib IS, Budin SB

Syst Biol Reprod Med, 2019 Jun;65(3):194-204.
PMID: 30773941 DOI: 10.1080/19396368.2019.1573274

Monosodium glutamate (MSG) is widely used in food preparation industry and has been consumed regularly. Previous studies had reported on effects of MSG when given at extremely high dosages, the results are not applicable to human equivalent intake. Therefore, the present study aimed to evaluate the effect of MSG on sperm quality and changes in reproductive organs of adult male rats when taken at average human daily intake (ADI). Twenty-four adult male rats were randomly assigned into three groups; NC (Normal control), MSG60 and MSG120 where MSG was given orally at 60 mg/kg and 120 mg/kg to each respective group. All treatments were conducted for 28 consecutive days. MSG at estimated ADI of 120 mg/kg body weight resulted in a significant drop in sperm quality (p

Electronic cigarettes (e-cigarettes) are handheld devices that deliver an aerosol by heating a solution made up of propylene glycol and/or glycerol with or without flavoring agents and nicotine. This nationwide cross-sectional survey examined factors associated with e-cigarette usage and reasons for its initiation among 13 162 Malaysian adolescents. Data from TECMA (Tobacco and E-Cigarette Survey among Malaysian Adolescents) were used. Nine percent of adolescents had used e-cigarettes in the past month. Males (adjusted odds ratio [aOR] = 4.08; 95% confidence interval [CI] = 3.36-4.95), 16 to 19 year olds (aOR = 2.64; 95% CI = 2.13-3.26), Malays (aOR = 2.25; 95% CI = 1.79-2.83), Sabah and Sarawak Bumiputeras (aOR = 2.25; 95% CI = 1.61-3.15), and cigarette smokers (aOR = 13.16; 95% CI = 11.14-15.54) were more likely to use e-cigarettes. Three main reasons for e-cigarette initiation among adolescents were its taste and smell, experimentation, and popularity. Sale of e-cigarettes with or without nicotine to people aged younger than 18 years should be banned. Flavored e-cigarettes should also be banned since there is evidence suggesting increased appeal among the younger generation.

Fulltext Alternative Tobacco Products Use among Late Adolescents in Kelantan, Malaysia

Yusof NA, Zin FM, Idris NS, Mohammad R

Korean J Fam Med, 2019 Jul;40(4):254-260.
PMID: 31109161 DOI: 10.4082/kjfm.18.0016

BACKGROUND: The rising prevalence of alternative tobacco and nicotine products (ATNPs) use among adolescents is a global concern that has been attributed to the reemergence of preexisting alternative tobacco products and emergence of new ones in the market. This study examined ATNP use among late adolescents. The association between ATNP use and reasons for using them was explored.
METHODS: This cross-sectional study conducted in 2016 involving 388 late adolescents from six government colleges in Kelantan, Malaysia, aged 18 to 19 years. They were requested to answer self-directed questionnaires with items on sociodemographic information and types of ATNP used. Other variables obtained include the environmental influence and reasons for using the products. Regression analyses between the dependent and independent variables were conducted using IBM SPSS ver. 20.0 (IBM Corp., Armonk, NY, USA).
RESULTS: The prevalence of ATNP use among late adolescents was 14.4%. The male sex, cigarette smoking status, and peer use were significantly associated with ATNP use. Several reasons for use were not significantly associated with ATNP use: perception of ATNP being less harmful and less addictive compared with cigarettes, curiosity, less expensive than cigarettes, to aid smoking cessation, and pleasurable flavors and taste.
CONCLUSION: The prevalence of ATNP use among late adolescents studying in government colleges in Kelantan is significant. There is higher perception on ATNP being less harmful and addictive than the conventional cigarette among the users compared with non-users. Significant associations are seen for the male sex, peer use, and concurrent cigarette smoking.

INTRODUCTION: The global market of flavour capsule cigarettes (FCCs) has grown significantly over the past decade; however, prevalence data exist for only a few countries. This study examined prevalence and perceptions of FCCs among adults who smoke across five countries.
METHODS: Cross-sectional data among adults who smoked cigarettes came from the International Tobacco Control Policy Evaluation Project Surveys-Brazil (2016/2017), Japan (2021), Republic of Korea (2021), Malaysia (2020) and Mexico (2021). FCCs use was measured based on reporting one's usual/current brand or favourite variety has flavour capsule(s). Perceptions of the harmfulness of one's usual brand versus other brands were compared between those who used capsules versus no capsules. Adjusted logistic regression models examined correlates of FCC use.
RESULTS: There were substantial differences in the prevalence of FCC use among adults who smoke across the five countries: Mexico (50.3% in 2021), Republic of Korea (31.8% in 2021), Malaysia (26.5% in 2020), Japan (21.6% in 2021) and Brazil (6.7% in 2016/2017). Correlates of FCC use varied across countries. Capsule use was positively associated with being female in Japan and Mexico, younger age in Japan, Republic of Korea and Malaysia, high education in Brazil, Japan and Mexico, non-daily smoking in Republic of Korea, and having plans to quit in Japan and Republic of Korea. There was no consistent pattern of consumer perceptions of brand harmfulness.
CONCLUSION: Our study documented the high prevalence of FCCs in some countries, pointing to the need to develop and implement regulatory strategies to control these attractive products.
